Comment 16 for bug 549679

I'm going to have to disagree with Krzysztof, and I am preparing an upload resolving this. I might agree if these functions we hidden in a plugin menu and not exposed on the default toolbar. Mario's comment above clearly explains that upstream intends this functionality to work out of the box. These indeed should be "strong, but not absolute, dependencies - i.e. something that should be installed in all but edge cases." The edge case is running this program on a distribution where these packages are not available.
